FASTENING MEANS.

Specification of Letters Patent.

Patented March 19, 1907.

Application filed August 1, 1906. Serial No. 328,754-

To all whom it may concern.-

Be it known that I, GEORGE 0. Olson, a citizen of the United States, residing at Chicago, in the county of Cook and State of lllinois, have invented certain new and useful Improvements in Fastening Means, of which the following is a specification.

This invention relates to means for fastening together and spacing apart a plurality of members, and is herein shown as employed in the construction of pocket savings-banks.

The object of the invention is to provide an eilicient fastening means which can be produced and applied at a minimum cost.

In the accompanying drawings, Figure 1 is a perspective view of the framework comprised in a ocket savings-bank, the side walls of sai bank bein represented as spaced apart and secured together by a fastening means embodying the features of my invention, a portion of one of the side walls being broken away to illustrate certain parts more clearly. Figs. 2, 3, 4, and 5 are views in a series lllustrating the steps taken in applying this fastening means. Figs. 6, 7, 8, and 9 comprise a similar series of views showing the application of a slightly-modified form of fastening means. Fig. 10 is a transverse section through the frame of the bank.

The savings-bank in which this fastening means is herein shown as employed is of a form suitable for carrying about in the pocket, and its framework consists, essentially, of two side walls 1 and 2, formed from an integral piece of sheet metal folded to provide a closed rounded edge 3. The side ed es of the walls 1 and 2 opposite to the close edge 3 and the shorter sides of said walls are secured together at a suitable distance apart by the means which constitutes this invention. Said means com rises a strut 4, formed from sheet metal, sai strut in this instance being substantially rectangular in form and bein provided at two of its opposite sides wit ugs 5 and 6 bent to lie at a right angle with the body of the strut. Said ugs in this instance are about one-third the width of the strut, thus forming shoulders 7 at each side of each lug. The struts 4 are set at suitable distances apart around the sides and ends of the framework of the bank, the side walls 1 and 2 bein provided with openings 8 and 9 to, receive t e lugs 5 and 6, respectively. In tl 1 e ;.process of forming the opening 8 in the wall 1 some of the metal is removed and a portion of the wall adjacent to said cut-away art pressed out of the plane of the wall to orm a seat 10 to receive the In 5. At one side of the opening 9 a seat 11 1s formed to receive the lug 6, and at the opposite side of said openin a portion of the metal is pressed inward (in the direction of the wall 1) to provide a tang 12.

In setting the strut 4 it is placed between the walls 1 and 2 in the position shown in Fig. 3. The framework is then placed in a suitable press by means of which the strut 4 is set in a position perpendicular to the walls 1 and 2, with the lugs 5 and 6within the seats 10 and 11, respectively, the portions of said lugs close to the body of the strut filling the openings 8 and 9, and the tang 12 forced back into the plane of the wall 2 behind the strut 4. The strut is thus held securely in place, the lugs 5 and 6 preventing outward or separating movement of the walls 1 and 2 of the bank and the shoulders 7 preventing inward movement of said walls.

In Figs. 6 to 9, inclusive, I have shown a form of fastening differing from that just described in that the tang 12 is punched outwardly from the wall 2 instead of being pressed inwardly. The strut 4 is set in substantially the same manner in both constructions.

In practice the framework of the bank is covered with leather or other suitable material. The form of fastening shown in Figs. 2 to 5, inclusive, ermits of setting the struts 4 after the frame ias been covered. The edges of the bank are closed in any suitable way, the struts 4 being provided with perforations 13 and lugs 14 for use in attaching the parts that close the edges.

While my invention is herein represented as employed in the construction of a pocket savings-bank, it will be understood that it may be used in various connections and that the fastening means is susceptible of modification to adapt it to s ecific uses. I therefore do not limit mysel to the precise details herein set forth, except to the extent indicated in the appended claims.

I claim as my invention 1. The combination with two walls, of a strut having thereon lugs bent at an a le with the body of the strut, seats in said we ls adapted to contain said lugs, and means for securing said lugs in their seats.

2. The combination, with two walls, of a shouldered strut having thereon lugs bent at an angle with the body of the strut, seats in said walls adapted to contain said lugs, and means for securing said lugs in their seats.

3. The combination, with two walls, of a shouldered strut provided at its ends with lugs, oppositely-facin seats in said walls for said lugs, and means or securing said lugs in their seats.

4. The combination, with two walls, of a strut/having lugs thereon adapted to engage said walls and a tang punched through one of said walls and adapted to engage said strut.

5. 'The combination, with two walls, of a strut adapted to engage said walls and a tang pressed from one of said walls and adapted to engage said strut to hold it in place.

he combination, with two walls, of a 5 extending at a right angle strut havin lu with the b0 y o the strut; seats for said lugs formed in said walls by pressing the material of said walls inwardly; and means for securing said lugs in their seats.

7. The combination, with two walls, each of which walls has an opening therein and a seat at one side of said opening, of a strut having lugs thereon adapted to lie in said seats and said openings, and means for securing said lugs in their seats.

8. The combination, with two walls, each of which walls has an opening therein and a seat formed at one side of said opening by pressing the material of said walls inwardly, of a shouldered strut having lugs extending at a right angle with the body of the strut, and a tang punched from one of said walls at one side of the opening therein, said tang'being ada ted to lie at one side of said strut and hold it m place.
